HeatGear® Armour is Under Armour's original performance baselayer, designed to be your first layer on and last layer off. Engineered for maximum comfort, it wicks away sweat and offers stretch for unrestricted movement. The super-light HeatGear® fabric provides superior coverage without adding weight, while mesh panels under the arms and on the back offer targeted ventilation to keep you cool. The material dries quickly and features anti-odour technology to prevent the growth of odour-causing microbes, keeping you fresh during intense workouts. With an ergonomic design that positions seams away from high-abrasion areas for enhanced durability, and a hybrid raglan sleeve construction for improved range of motion, this baselayer is built for performance and comfort.
